25 * MarketUploader is a class that handles the uploading of market
26 * data from Yohoho! Puzzle Pirates via the Java Accessibility
29 * MarketUploader initializes after the main YPP window has

33 * submitted to the YARRG and PCTB servers. If any errors occur,
34 * an error dialog is shown, and processing returns, the button
35 * becoming re-enabled.
